https://devzone.nordicsemi.com/f/nordic-q-a/29857/nrf52810-bootloader-no-timeout-when-ota-failsHi, I'm using nRF52810 on SDKv14.2 and I have changed the bootloader from 52832 to work for 52810. I could do OTA now. I found that the bootloader there is no timeout when OTA fails. So I add a watch dog when DFU start. This way works good for nRF52840en-USTelligent Community 13Tue, 14 Nov 2017 10:43:53 GMT
